Detailed Description
The scope of the present invention is not limited to the specific language used in the description of the embodiments or illustrations, and the same reference numbers may be used in the embodiments. When a component is "connected to" or "coupled to" another component, it can be directly connected or coupled to the other component or intervening components may be present.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a block diagram illustrating an adapter according to an embodiment of the invention. Fig. 2 is a schematic diagram of an adapter module according to an embodiment of the invention. Referring to fig. 1 and 2, the adapter module 10 of the present embodiment is, for example, an extended line power socket device. The adapter module 10 of the present embodiment mainly includes an adapter 100 and a power line 200. The adapter 100 is adapted to interface with a power cord 200. In the present embodiment, the power line 200 has a first connector 210 and a second connector 220. The first connector 210 is adapted to interface with the adapter 100, and the first connector 210 is adapted to be configured with a trigger 212. In addition, the second connector 220 is adapted to be electrically connected to an external power source 300. The external power supply 300 is, for example, commercial power. In addition, the adapter 100 of the present embodiment mainly includes a first interface 102, at least one second interface 104, an identification circuit 110, a controller 120, and a detection circuit 130.
Fig. 2 mainly shows the configuration relationship among the power line 200, the identification circuit 110 and the controller 120 in the adapter module 10, and therefore, other components are not shown. The power cord 200 is described by taking a power cord dedicated to the adapter 100 as an example. In addition, the first interface 102 is, for example, an input port of the adapter 100, and the second interface 104 is, for example, an output port of the adapter 100. The second interface 104 in fig. 1 is illustrated as an example, and the invention is not limited thereto.
As mentioned above, in the present embodiment, the first interface 102 is configured to be plugged by the first connector 210 of the power line 200. The second interfaces 104 are adapted to electrically connect with at least one load 400. The load 400 is, for example, various electronic devices or electrical appliances, and the invention is not limited thereto. In addition, the load 400 in fig. 1 is illustrated as an example, and the present invention is not limited thereto. In addition, the identification circuit 110 of the present embodiment has a sensing switch 112. The inductive switch 112 is disposed at the first interface 102. It should be noted that, in the present embodiment, the inductive switch 112 changes the on-off state according to whether the first connector 210 provides a trigger, and correspondingly generates a first message. Further, the first connector 210 of the present embodiment can be configured with a trigger 212, and when the first connector 210 is inserted into the first interface 102, the inductive switch 112 configured at the first interface 102 can be triggered by the trigger 212 to change the on-off state. For example, the inductive switch 112 disposed at the first interface 102 can be triggered by the trigger 212 to be turned on.
In a preferred embodiment, the inductive switch 112 may be a reed switch and the triggering element 212 may be a magnetic element. Therefore, when the first connector 210 is inserted into the first interface 102, the reed switch can be triggered by the magnetic member, so as to change the on-off state. For example, when the first connector 210 is inserted into the first interface 102, the reed switch may assume a conducting state. In other embodiments, the trigger 212 may be a protrusion formed on the first connector 210, and the inductive switch 112 may be a pressing structure disposed in the first interface 102. Therefore, when the first connector 210 is inserted into the first interface 102, the pressing structure disposed in the first interface 102 can be substantially pressed by the protruding structure formed on the first connector 210. The on/off state of the inductive switch 112 can be changed by the above-mentioned trigger action, such as substantial pressing. For example, when the first connector 210 is inserted into the first interface 102, the inductive switch 112 can be in a conducting state. In other words, the triggering of the inductive switch 112 by the triggering component 212 can be a non-contact triggering and a contact triggering, and the invention is not limited thereto.
In the above embodiments, the trigger 212 is configured to define a type or a specification of the power cord 200. In detail, the power cord 200 configured with the triggering member 212 is, for example, a dedicated power cord of the adapter 100 of the present invention, which has a better safety factor. In contrast, the power cord without the trigger, such as the power cord sold in the market, may not satisfy the safety factor of the adapter 100. That is, the present invention can define the type, specification or related safety factor of use of the power cord via the setting of the trigger 212.
On the other hand, the controller 120 of the present embodiment is electrically connected to the identification circuit 110 and receives the first message. In addition, the detecting circuit 130 is electrically connected between the first interface 102 and the second interface 104. The detection circuit 130 detects a power parameter value between the first interface 102 and the second interface 104 and provides a second message to the controller 120. The power parameter value is, for example, a current value. In the present embodiment, the first message includes, for example, whether the first connector 210 provides the trigger, and the second message includes an actual current value between the first interface 102 and the second interface 104.
It should be noted that the controller 120 of the present embodiment can define a rated current value (rated current) corresponding to the power line 200 plugged into the first interface 102 according to whether the first connector 210 provides the trigger. In detail, the controller 120 defines a rated current value corresponding to the power line 200 according to the on/off state of the inductive switch 112. Further, when the actual current value is greater than or equal to the rated current value, the controller 120 may send a prompt message. In other words, the controller 120 of the present embodiment can send the prompt message according to the received first message and the second message. The on/off state of the inductive switch 112 is, for example, an on state or an off state.
For example, the rated current value of the power cord 200 configured with the triggering member 212 may be 20A, and the overall load that the adapter module 10 can bear may be 2000 VA. In contrast, the power line without the trigger 212 has different load capabilities, and the controller 120 of the present embodiment directly defines that the load capability is smaller than that of the power line 200 for safety reasons. For example, the rated current value of the power line without the trigger 212 is 15A. In this way, in the case that the adapter 100 is matched with a power line without the trigger 212, if an excessive load is inserted into the second interface 104 of the adapter 100, which results in an actual current value between the first interface 102 and the second interface 104 being equal to or exceeding 15A (rated current value), the controller 120 will send a prompt message.
In the present embodiment, the adapter 100 may include a prompting unit 140, for example. The prompting unit 140 is, for example, an alarm device. The prompt unit 140 may be electrically connected to the controller 120 and receive the prompt message. Therefore, when the actual current value is greater than or equal to the rated current value, the controller 120 can send an alarm such as a sound source or a light source through the prompting unit 140, so that the user can notice the safety in use.
Further, in order to provide the adapter module 10 of the present embodiment with better safety, the adapter 100 of the present embodiment may further include a switch unit 150. The switch unit 150 of the present embodiment is electrically connected between the first interface 102 and the detection circuit 130. In this way, the controller 120 can control the on/off state of the switch unit 150 according to the first message and the second message. In short, when the controller 120 determines that the actual current value is greater than or equal to the rated current value, the controller 120 may not only issue a warning through the prompting unit 140, but also the controller 120 may control the switch unit 150 to turn off to stop the power supply from the external power source 300 to the load 400. Even more, the controller 120 may control the adapter 100 to ramp down the rated output current of its second interface 104, for example, from 20A to 15A. Therefore, the present embodiment can further ensure the safety of the power line in use, and avoid the danger of the power line not provided with the trigger 212 due to insufficient load capacity. The on/off state of the switch unit 150 is, for example, an on state or an off state.
In addition, the adapter 100 of the present embodiment may further include a battery 160. The battery 160 is electrically connected between the switch unit 150 and the second interface 104. Accordingly, when the switching unit 150 is turned off, the controller 120 may control the battery 160 to supply power to the load 400. As a result, after the external power source 300 stops supplying power to the load 400, the load 400 can still obtain the power required for operation by the battery 160.
In addition, the adapter 100 of the present embodiment may further include a circuit board 170, a third interface 180, and a power supply unit 190. The controller 120, the third interface 180, and the power supply unit 190 are disposed on the circuit board 170, for example. The inductive switch 112 is electrically connected to the third interface 180, the power supply unit 190 provides power for the inductive switch 112 through the third interface 180, and the controller 120 is electrically connected to the identification circuit 110 through the third interface 180. In the present embodiment, the power supply unit 190 is, for example, an independent power supply component, so that the inductive switch 112 can continuously sense whether the first connector 210 of the power line is provided with the trigger 212, and the controller can effectively determine whether the power line has sufficient load capacity to perform the power supply operation of the load 400. Of course, in a preferred embodiment, the external power source 300 can also directly provide the power applied by the inductive switch 112 through the first interface 102, and the invention is not limited thereto.
In summary, the present invention arranges the trigger on the power line dedicated to the adapter, so that the adapter of the present invention can effectively sense whether the power line inserted therein is of its dedicated specification, and further determine whether the power line has sufficient load capacity to perform the power supply operation of the load. If the power line does not have enough load capacity to carry out the power supply operation of the load, a prompt message is sent out to remind the user. Of course, the present invention can also disconnect the power supply from the external power source to the load by the arrangement of the switch unit. In other words, the adapter module of the present invention has better safety in use.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
